To all whom it may concern: 7 Be it known that I, ERIC 'BYLUND, a 01131-zen of the Dominion of Canada, residing at the city of Winnipeg, in theProvince of Manitoba, Canada, have invented certain new and usefulImprovements in Hose- Couplings, of which the following is aspecification. I

My invention relates to improvements in couplings used on fire andgarden hose, and similar flexible fluid carriers, and the objects of theinventionare to provide a coupling free from the objections which attachI to the screw form of couplings now in every.

'day use. I

I attain my object by the means set outin the following specificationsand claims, and fully illustrated in the accompanying drawings in whichsimilar characters of reference refer to similar parts throughout.

Referring to these, Figure -1 is anelevation of my coupling as it wouldappear when connecting two lengthsof hose and ready for use. Fig. 2shows the coupling open and ready toreceive the end of a length of hose.Fig. 3. is a hose connection ready to be placed in the coupling. Fig. 4.is an end View of the couplin in its opened position.

Fig. 5 is a view 0 the locking pin which maintains the coupling inclosed position, with the securing device in operative position. Fig. 6is a fragment of the locking pin, with the'securing device inin-operative position. Fig. 7 is a fragment of the locking pin, showingthe forked end in which the securing device is located. Fig. 8 shows thesecuring device separate from the looking pin. Fig. 9 represents onestyle of packing which maybe used to secure a watery tight joint betweenthe pipes. Fig. 10 shows a male hose connection fitted with a differentstyle of packing. Fig. 11 is a view of the opposite or female hoseconnection. Fig. 12 is the packing retainer and Fi 13 is an end View ofthe second style 0 packing. Fig. 14 illustrates on a' reducedscale, acomplete coupling embodying the features shown in Figs. 10, 11, 12 and13, a portion of the coupling members being broken away to show thedetails of the connection.

. half-of the coupling is indicated by the later A' andtheopposite halfby the letter B. C is a piece of flexible hose terminating in a metalend D, which forms a permanent part of'the coupling. E. is a similarpiece of flexible hose termlnating in the metal end F, which 1s adaptedto be embraced between the'parts A and B of the coupling, in the 1 tmanner hereinafter described, thus eflecting a j unction between thelengths of hose represented as (land E.

As shown the coupling proper consists of the parts "A and B permanentlyhinge .connected with'each other in,butt fashion by a pin 1 WhlCllpasses through an intercommunately lnterconnecting parts 2 and 3pertaining respectively to the members A and '7 B. Similarly the outeredges of the members A and B are furnished with projections 4 and 5,those on the one part being adapted to interconnect alternately withthose on the other, the projections 4 having a longitudinally alinedopening 6 passing through them from end to end, adapted to register witha similarly disposed passage? through the projections 5, when the partsare brought together.

It will be noted that the openings 6 and 7 alined passage -,through thealterform a continuous passage through the parts 7 secured in the fork 9by a stud 10 which passes through both prongs of the fork 9 and theopening 11 in the member H.

The part 12 of the member H is flattened on both sides so that it mayoperatively fit in the fork 9, to the shape of which it conforms both incross and longitudinal dimension. The end 13 of the member H is circuhrin shape and of thesame diameter approximately, as the end of the pin G.

When it is desired to lock the parts A and B of the couplingtogether,the member His placed in the position shown in Fig. 6,

' one side and the point of the portion 12 upon the opposite side, inwhich position the pin G is efiectually secured from accidentaldislodgment. I

As previously mentioned the part 12 of the member H fills the fork 9lengthwise, so that when placed longitudinally the point of the portion12 is in contact with the end 14 of the fork 9, in which position,should there be any dificulty met with in removing the pin G the head 13of the member H may be struck with a hammer or any other suitable toolwithout damage to the. stud 10,

and the pin G driven from its seat.

lit is preferable that the metal end D of the hose C should form apermanent part of the coupling and remain secured to the part B thereof,as shown in Fig. 2, thus forming a female end, while the opposite end ofthe same would be a male end similar to F in Fig. 3, adapted to bereceived by a coupling similar to that under description. The interiorof the end of the pipe D is beveled out as shown by the dottedlines 15in Fig. 2 for the reception of the end 16 of the pipe F which is taperedto fit therein.

17 indicates a ring packing preferably of rubber which follows the innercircumference, of the pipe D, the tapered part 16 of the pipe F beingprovided with a groove 20 to receive the packing when the pipes arebrought together. The beveled part of the pipe D, is grooved to retainthe packing in position when the coupling is opened, and the hoseconnection broken.

The numerals 18 indicate inwardly extending ribs adapted to enter thegrooves wardy past the surface of the (pipeD for the 19 around thecircumference of the pipes D and F. it will be noted that the ribs '18are beveled upon that side of them nearest the center of the coupling,and that the grooves in the pipes are cut with a beveled side to match;

It will be noted that the packing 17 is of a thickness which allows itto encroach inpurpose about to be explaine As previously stated the pipeD preferably forms a part of the couphng: in order to connect with thel'lOSQI'E it is only necessary to place the pipe F in the part B withits tapered portion 16 within the end of the pipe D and close the part Adown upon it.

The ribs 18 will enter the grooves 19 on both pipes, and as the pipe Dis stationary, the bevel on the face of the ribs 18 will operate uponthe beveled faces of the grooves 19 to draw the pipe F forward.

The packing 17 will enter the groove 20 on the part 16 of the pipe F andbe compressed, thus insuring a water tight joint between the pipes D andF. As the locking pin Gis tapered it assists as it passes through theopenings 4 and 5 to bring about this result. When the pin G is in placethe member H is turned to the position shown in Figs. 1 and 5, when thepin G is eifebtually prevented from being removed till the member H isagain brought into longitudinal alinement with it.

It is of course obvious that the ring packing 17, could be secured inthe groove 20 on the beveled part 16 of the pipe F, instead of in theinterior of the pipe D with the same result.

Figs. 10, 11, 12 and 13 illustrate a somewhat diii'erent form pf packingand the means used to retain it in position. By reference to Fig. 10 itwill be seen, that the mouth of the pipe D is beveled back interiorly at15 as in the previous description, and is further interiorlyscrew-threaded at the rear of the bevel to receive the screwthreadedportion 21 of the packing retainer J, ig. 12). The retainer J consistsof three parts, the screw-threaded portion. 21, the forwardly beveledportion 22 and the connecting portion 23 the diameter of which is lessthan that of the parts 21 and 22 with which it connects. The face of thebeveled portion 22 is provided with longitudinally extending grooves 24for a purpose to be explained. A circular rubber packing 25 is disposedon the member if, encircling and occupying the full length of theportion 28 thereof, the parts 21 and 22 forming shoulders at either endto retain it in position.

The packing 25 is, it will be understood,

of peculiar shape, that portion of it abutting on the screw-threadedportion 21 of the retainer being tapered back to entirely fill thespace, between the part 23 of the retainer and the beveled part 15 ofthe pipe D when the retainer J is screwed into the pipe D, which is doneby the use of a spanner in the holes 26 in the end of the part J.

The front of the packing 25 is beveled forward and vback to form withthe part '22 of the part J the alternate concentric projection 27 anddepression 28, and the end of the pipe F? (Fig. 11) is formed with adeep concentric groove '29 shaped to receive the projection 27, aprojection 3O to lit the depression 28 andan interiorbevel 31 to matchthe bevel of the part 22 of the member J when the ends ofthe pipes D andF are brought together. When the pipes have been brought together andare secured in the coupling as previously described, and fluid hasentered the pipes under pressure a portion of it passes up the face ofthe part 22 by means of the grooves 24 and exerts a pressure on theinner face of the projecting. portion 27 of the packing thus forcing itout against face of the groove 29 in the end of the pipe F and forming awater tight joint between-the two.-

From the foregoing description it will beseen that my invention is awide departure from the forms of coupling previously used.

The older forms for. the most part depend upon the accuracy of screwthreads for their effectiveness. These are entirely absent from mycoupling, and all the attendant difliculties met with in freezingweather are avoided. Y

My coupling is quick and accurate and no special tools are required tooperate it. The only part of the coupling liable to deterioration in anyway is the ring packing, and as this maybe of the styles described orany other deemed desirable, and as it may beremoved and replaced withoutdifficulty, it becomes rather an advantage than a drawback.

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent, is,-.
